人工正电场是利用220伏特的高压电源和场源装置,在蔬菜苗圃施加正电场。据重庆医科大学等单位试验证明,能明显地提高叶绿素含量,使蔬菜增产。当辣椒苗圃长出 2片真叶对外加人工正电场13天,叶色明显增绿,据测定叶绿素的最大增加率高达52％左右,增产达34％。对黄瓜进行试验,增产幅度高达41％左右。此方法无 The artificial positive electric field uses a 220 volt high voltage power supply and field source device to apply a positive electric field in vegetable nurseries. According to Chongqing Medical University and other units proved that can significantly increase the chlorophyll content of vegetables to increase production. When paprika nursery grow 2 true leaves on the artificial plus electric field for 13 days, the leaf color increased significantly green, it was determined that the maximum increase rate of chlorophyll up to 52%, an increase of 34%. Test the cucumber, increase production rate as high as 41%. None of this method
